Chanel College is inviting participants to its Caritas Challenge this weekend to walk for 24 hours in support of the Philippines rebuild.
The challenge, undertaken in Lent, will see teams walking from 1pm Saturday to midday Sunday on the college's athletic lawn.
College spokeswoman Bronwyn Hallot says it is the second year the college has run a challenge.
"This year, the focus is for the Philippines - Build Back Better.
"The Philippines has been hit with storm after storm, they're still rebuilding.
